02 / Project timeline

Build the home. Prepare the site. At the same time.

A traditional build moves through on-site construction. Prefabrication allows two work streams to move forward together, once approvals and site requirements are resolved.

Potential time saved

To be confirmed against real project timelines.

— weeks estimate pending

Indicative stages, not a guaranteed completion schedule. Approval pathways, terminology and timing vary by state and property. No total Haven delivery time is assumed.

03 / What makes the difference

Less uncertainty. A considered choice.

Same compliance standard

NCC Class 1a applies to a permanent home, whether prefabricated or built on site. Site-specific approvals and certification still matter.

A clearer cost picture

A fixed-price prefab scope can provide certainty once confirmed. Traditional builds can face cost changes; either option needs clearly agreed inclusions and allowances.

More work in parallel

Preparing your site while the home is produced and shipped can shorten the overall schedule. Actual timing depends on approvals, freight and your property.

Single-day crane installation

The crane installation stage takes one day on a prepared, accessible site. Connections, inspections and occupation certification follow before handover.
